COMBINED ROSE AND ESCUTCHEON.

SPECIFICATION forming part of Letters Patent N0. 530,562, dated December11, 1894. Application iiled March 10,1894. Serial No. 503.107. (Nomodel.)

To `LZZ- whom t may concern: s

Be it known that I, CHARLES R. UHLMANN, a citizen of the United States,residing at Peoria, in the county of Peoria and State of -Illinois, haveinvented certain new and useful Improvements in a Combined Rose andEscutcheon; and I do hereby declare that the following is a full, clear,and exact description of the invention, which will enable others skilledin the art to which Vit appertains to make and use the same.

This invention relates to improvements in escutcheons.

The object is to provide an escutcheon with a simple device to lock thekey in its place when so desired, to prevent its being turned in thelock from the outside ot' the door.

In the drawings presented herewith, Figure l represents a front view ot'the escutcheon, showing a knob and catch, and showing a section of thekey in place. Fig. 2 is a back view of the escutcheon showingtheoperating parts. Fig. 3 is also a backview of the escutcheon showingthe main plate removed] Fig. 4 is aview of a modified form of the de-lvice, showing a section of a key held in the locking mechanism. Fig. 5is a sectional ele-` vation of the form of device shown in Figs. 1, 2and 3 inclusive, showing its application` to a door and lock, andshowing a key andl its relation to the locking parts. Fig. 6 is asectional elevation of the form of escutcheon shown in Fig. 4, and Fig.Z is a perspective view of a section of the form of escutcheon shown inFigs. I and 6 showing a key as held by the device.

In the figures the escutclleon body is rep-l resented at A, having theflange B extending entirely around its edges and also having the usualrose C for the knob. The keyhole is shown at D and in Figs. l and 5 thekey E is shown in place. Near the upper end of the escutcheon is cut aslot F having a lug G at the middle ot' its length, so as to form twonotches.

In Figs. l, 2, 3 and 5 at either side of the keyhole D is cut a slot Hand H', the purpose of which will be hereinafter described.

The construction of the working parts may now be understood.

A plateIof the general form shown in Fig. 3 rests against the back ofthe escutcheon and is provided with anapertureJ which engag'esvwith apost K formed with the body of the device. The said post K acts as apivot and allows the said plate to swing thereon. A second post L isformed with the said body A above the post K, upon which is pivoted anupper locking plate M to be described.

The plateI is slotted at N so that the plate may swing on the post Kwithout interfering with the post L.

The plate M is substantially of the form shown in the drawings andisprovided with an aperture O, through which the post lL is let as theplate is put into position against the plate I and a slot P is cut insaid plate M so that the post K is not interfered with. A lug Q is madewith the under side of the plate M to enter a slot R cut in the plate Isubstantially at right angles to the slot N. It Will now be seen thatthe plate I is pivoted on the post K and the'plate M on the post L andit will be seen that by throwing the plate M in one direction the plateI will be thrown in the opposite direction by reason of the lug Qworking in the slot R of the said plate I. With the lower extremity ofthe said plate I is formed the projection S carrying a lug or pin Twhich extends `through the slot H in the `body A, and formed with thelower eX- tremity of the plate M is also a projection U `opposite theprojections` on the plate I, and

which is provided with a pin V` which extends through the slot H. Theplates I and M are held in their respective places by a sliding key W.The posts K and L are each provided with a notch 1K and L respectively,and these' notches form a key way for the said key W. By this means theplates are held in their places and at the same time are allowed to movefreely on their pivots. The form of key is shown at E in Fig. 5 and inwhich a lug b is shown, which is made with the key on a line with thelugs T and V. Now with the pins or lugs T and Vin the position shown inFig. l, i. e., with the said lugs separated, the key may be turned inthe lock, but should the lugs be brought together the lug b on the keycomes in contact with the said lugs and cannot be turned. The throwingof the lugs is accomplished by a knob M2 se` cured to the upper end ofthe plate M, which engages with the notches of the slot F. The

IOO

said plate M is preferably made of spring steel and the flexible steelkeeps the knob in engagement with the said notches, and by the pressingof the knob away from engagement with the notches and throwing said knobin either direction, the said lugs T and V are actuated.

The modified form of my invention and the form which I most prefer isshown in Figs. 4,16 and 7 and in which M represents the plate which isnearly of the same form as that shown in Figs. 1, 2, 3 and 5 abovedescribed, with the exception of the extremity at'which is elongatedfrom the body of the plate and is provided with a slot or notch d whichengages the key E when in the position shown in-Figs. 4 and 7, and whenthrown to the opposite side the key is released. This is the simpler andbetter form of lock, but it may be varied in construction to allow a keyof anyshape of cross section being used and the forms in Figs. 1, 2, 3and 5 may be varied also so that a key of any shape and with er withoutthe lug b may be used.

The mode of keeping the plate M in place is substantially the same asthat described for the other forms, and the device is operated bysubstantially the same means.

All parts may be varied slightly in their construction and still attainthe same results.

By the use of the device herein described and shown the key may beprevented from being turned in the lock from the outside. The escutcheonbeing on the inside of the door the knob M2 may be thrown in a directionto engage the lower portions with the key.

It is not necessary that the plates M and I should be pivoted on theescutcheon, as they may be placed in any working manner to get theresults desired. The knob M2 for actuating the plate M may be placedabove or below or on either side of the key-hole and the said plates Mand I may be placed either within or on the outside of the escutcheon.

I claim- 1. In a key locking device for escutcheons, the combination ofan escutchcon having a single locking plate M pivotally mounted therein,substantially as set forth, the upper extremity of said plate forming aspring, a knob M2 secured to the said upper extremity ot' the plate forengagement with the escutchcon, a recess formed in the lower extremityof the plate, a slot or notch d cut in said extremity and forming partof said recess, and a key E engaged by the said slot d substantially inthe manner and for the purposes Set forth-and described.

2. In a key locking device for escutcheons, the combination of anescutcheon, a plate M pivotally mountedtherein on the post L, a post Ksituated below the post L on the escutcheon, a slot P in the plate M forallowing the said plate to swing, a key W secured between the said postsL and K for keeping the plate M in place, a slot d made in the lower endof said plate M, the key E adapted to be engaged by said slot d, aspring tongue forming part of the upper part of the plate M, a knob M2onsaid tongue and a slot F and lug G in said escutcheon as set forth, forengagement with said knob M2 substantially as and for the purposesdescribed.

3. In combination with an escutcheon, a post K made with the saidescutcheon and having a plate I pivotally mounted thereon, said plate Icarrying at its lower extremity a pin or lug T substantially in themanner and for the purpose set forth, a post L made with the saideseutcheon and having a locking plate M pivotally mounted thereon, saidplate M being in working engagement with said plate I by suitable means,the lower extremity of said plate M having a pin orlug V for thepurposes set forth and means for locking said plate M when in anyposition for the purpose herein described and shown.

4. In a combined rose and escutcheon, a key-lock comprising a plate Isecured in working position on the escutcheon, a locking plate M alsosecured in working position on said escutcheon for actuating the saidplate I substantially in the manner and for the purposes set forth, saidplate M having a knob M2 secured thereto and operated from the outsideof the device above or below the key hole or on either' side thereof forthe purposes set forth.
